Not sure why, but people seem interested in the “history of climate blogging”. See posts here and here, for example (there may be more, if so, they are hopefully linked). And I see Eli has already nicked my title, but for different purposes.
My first post was Jan 2005, some climate stuff came within a few months. Not really that long after Stoat and RC, then. But I didn't (and still don't) think of it as anything particularly revolutionary or trend-setting, it was just that the previously well-established discussion fora of usenet which had served their purpose well for many years were finally dying due to a surfeit of nuisance-makers and lack of moderation. I'm still not really a fan of the concept of blogs (too much of a personal soap-box for proper discussion) but they still seem to be the worst system available, apart from all the other ones. I was on sci.env a decade earlier (at least occasionally; climate change wasn't high on my agenda during my maths DPhil).
But one thing that thinking back on this does perhaps help to explain, is my cynicism at the supposed new dawn of revolutionary new(bie) climate bloggers trying to be nice to sceptics, in the hope that this will make a material difference to anything at all. It hasn't, and it won't. That Watts should post something likening climate scientists to Hitler, soon after having a supposedly collegial dinner with several of them, should surprise no-one. Plus ça change (scuse my french, I've just had mussels for dinner). That the scientists respond by writing an article for his blog basically excusing him for having posted it...umm...that worked well. For him.
